LAUDATIO-Repository REST API
Documented, versioned, public read API of the LAUDATIO-Repository (Long-term Access and Usage of Deeply Annotated Information), the open-access research-data repository for historical linguistic corpora operated by HU's Department of Corpus Linguistics with the Computer- und Medienservice. HU publishes its own API reference at /docs/elasticapi naming 32 paths across corpora, documents and annotations; live probe 2026-09-01 returned 30 corpora, 5,284 documents and 1,160 annotation layers. Classified `institution` despite the laudatio-repository.org domain because every ownership signal is HU's: the site imprint and privacy policy point at hu-berlin.de, sign-in authenticates HU accounts against HU's Shibboleth IdP, the source is on HU's own GitLab, and DOIs are minted under HU's DataCite membership as repository tib.hu-laudatio. This surface was missed entirely by the June 2026 profile.
